Earlier this season, Mourinho and his assistants disgraced themselves in a shameful spat which saw Roma goalkeeping coach Nuno Santos involved in a physical altercation with Bodo/Glimt boss Kjetil Knutsen.
Both men claimed self-defence, but both were suspended by UEFA, infuriating Knutsen, who was disgusted by not only by Santos and the suspension, but also Mourinho.
Knutsen said: "[Mourinho's] type of attitude is shocking. His values and his way of coaching are so far from what I represent. It’s incredibly disappointing to see such behaviour from a coach with so many titles and who has been part of the sport for such a long time."
Nobody else who has followed Mourinho's career was in the least bit surprised, of course. He has plenty of previous, so there was little shock when he found himself at the centre of another ugly episode just a few days later, when another member of Mourinho's coaching team disgraced himself by mocking Salernitana over their potential relegation from Serie A.
Mourinho apologised and yet even then couldn't resist a snide comment of his own, with the 59-year-old electing to take yet another shot at Bodo-Glimt.
"We are civilised people, what happens on the field ends there," he said without a trace of irony. "Nobody will be waiting outside 45 minutes later to punch someone in the face."
However, Salernitana director Walter Sabatini wasted little time in tackling Mourinho's claim that he and his staff were "civilised", accusing them of "ignoble behaviour".
“With every refereeing decision, everyone pours onto the pitch from the bench, it’s unjustifiable," he fumed in an interview with DAZN. "We can lose to Roma, but not like this.
"I know full well that as soon as he hears this he will say I’ve never won anything and therefore cannot speak. I have not won 25 trophies, but I am a serious person and deserve respect nonetheless. But I see arrogance [in Mourinho]."
He's not the only one. In Roma's very next league outing, against Napoli, Mourinho accused the officials of conspiring against his side. An unsurprised Luciano Spalletti simply refused to dignify that claim with a response.
